Competing Higher Order Topological Superconducting Phases in Triangular Lattice Magnet-Superconductor Hybrid Systems
Ka Ho Wong, Jacopo Gliozzi, Mark R. Hirsbrunner +4
We demonstrate that a plethora of higher order topological phases emerge in magnet-superconductor hybrid (MSH) systems through the interplay of a stacked magnetic structure and an…
Anomalous crystalline-electromagnetic responses in semimetals
Mark R. Hirsbrunner, Oleg Dubinkin, Fiona J. Burnell +1
We present a unifying framework that allows us to study the mixed crystalline-electromagnetic responses of topological semimetals in spatial dimensions up to through dimens…
Crystalline-electromagnetic responses of higher order topological semimetals
Mark R. Hirsbrunner, Alexander D. Gray, Taylor L. Hughes
Previous work has shown that time-reversal symmetric Weyl semimetals with a quadrupolar arrangement of first-order Weyl nodes exhibit a mixed crystalline-electromagnetic response.…
Beyond MP2 initialization for unitary coupled cluster quantum circuits
Mark R. Hirsbrunner, Diana Chamaki, J. Wayne Mullinax +1
The unitary coupled cluster (UCC) ansatz is a promising tool for achieving high-precision results using the variational quantum eigensolver (VQE) algorithm in the NISQ era. However…
